Table 105. systemerase
Description Allows you to erase the components to remove the server from use.
Synopsis
● To erase a specific component.
racadm systemerase <component>
● To erase multiple components.
racadm systemerase <component>,<component>,<component>
Input
● <component>—the valid types of components are:
○ bios—To reset the BIOS to default.
○ diag—To erase embedded diagnostics.
○ drvpack—To erase embedded OS driver pack.
○ idrac—To reset the iDRAC to default.
○ lcdata—To erase Lifecycle Controller data.
○ allaps—To reset all apps.
○ secureerasepd—To erase the physical disk. This supports SED, NVMe drives, and PCIe cards
○ overwritepd—To overwrite physical disk. This supports SAS and SATA drives.
○
percnvcache—To erase NV cache.
○ vflash—To erase vFlash.
○ nvdimm—To erase all NonVolatileMemory.
NOTE: When BIOS is selected for System Erase, the server is turned off and the iDRAC is reset at the
end of the Automated Task Application. To complete the process of BIOS reset, the server power must
be restored. When the server is turned on, during POST, the BIOS completes the process of resetting
to the default properties. At the completion of the reset process, the server is again turned off.
Resetting the BIOS also includes the erasing of BIOS-related nonvolatile settings that are used by the
OS and embedded in the UEFI applications.
NOTE: When the racadm systemerase command is executed, the iDRAC will take the following actions
if the:
● Server is powered off—it is powered on.
● Server is powered on—a graceful system reboot will be executed.
● ACPI is enabled on the server— a graceful shutdown occurs within a minute or two.
● ACPI is not enabled—a forced shutdown occurs and it may require up to ten minutes to complete.
Following the server reboot, the Lifecycle Controller will execute the System Erase job to carry out the
requested actions. All actions performed by the System Erase operations are recorded to the Lifecycle
Log, including details of all devices erased. When these actions are completed, the server will be
powered off and remain in this state, allowing service personnel to perform any needed posterase
actions such as drive removal or hardware reconfiguration. When the server is powered on to return to
service, the Lifecycle Controller will collect the system inventory and reflect any hardware or firmware
changes made after the System Erase.
Examples
● racadm systemerase bios
